rThis invention relat s to preparations for counteracting and partially inhibiting perspiration and more particularly to a dispenser against which the fingers are adapted to be rubbed or patted to dust on the fingers a preparation which counteraots the perspiration and reduces the formation thereof.

It is generally well known that in some industries, such as in the processing of fine fabrics and where polished metal parts easily susceptible to corrosion are handled by the workers, every precaution must be exercised to prevent injury or damage to the materials handled by reason of the perspiration on the workers hands and fingers. lin many such industries the nature of the work requires extremely high sensitivity of the finger tips, and the use of gloves and other protectors is therefore impractical.

it is an object of this invention to provide a dispenser which is adapted to be readily contacted by the fingers to neutralize perspiration and to retard, to some extent, the formation thereof.

Our invention contemplates a dispenser containing or formed of a preparation which includes balanced proportions of the perspiration neutralizer and perspiration inhibitor, the proportions being determined such that, although the perspiration on the finger tips is instantly and completely neutralized, its formation is not altogether prevented. We have found that ringer tips are moet sensitive when they are clean, smooth and slightly moist. Our dispenser is designed to maintain the finger tips in this condition and is also designed such that the preparation can be applied to the fingers very readily and without interrupting the users activity to any appreciable extent. l

In its broader aspects the invention contemplates a dispenser adapted to be contacted by the finger tips to dust thel fingers with a preparation containing an anti-perspirant, an acid neutraliser and a suitable carrier. As anti-persp-irants, the use of aluminum sulphate is preferred; but the sulphate salts of other metals, such iron, bismuth and zinc, may be employed if desired.. These compounds tend to inhibit the formation of perspiration, and their use for this purpose is generally well known.

The neutralizer or anti-acid component of our preparation is preferably magnesium' carbonate, although other carbonatos, such as sodium bicarbonate and potassium bicarbonate, may also be employed. Magnesium carbonate is preferred because of its stability, that is, it is practically insoluble in water and yet readily soluble in water saturated with carbon dioxide with which it cornbines to form magnesium bicarbonate. Thus, in the presence of body wastes, such as perspiration which usually contains carbon dioxide, the magnesium carbonate becomes active and serves as a neutralizer while, at the same time, it is not subject to deterioration merely from contact with humid air or in the presence of a moist atmosphere. Any inert powder material, such as common talc, Venetian talc, French chalk, etc. is suitable for use as the carrier in our preparation.

The ab-overn entioned ingredients require no special mixing procedure and may be incorporated in the preparation by mixing them in the following general proportions by weight:

140% of anti-perspirant Ztl-30% of carrier material -Sl% of neutralizer We have found that, when the abovementioned ingredients are combined in the above proportions, a very stable and effective preparation is produced. As an example of more specific proportions of the above ingredients which we have found to be very effective the following composition is suggested:

l part aluminum sulphate 20 parts Venetian talc 43 parts magnesium carbonate It will be noted that in every instance the neutralizer or anti-acid component forros the `dominant proportion of the preparation and the quantity of anti-perspirant is less than one sixth the proportion of anti-acid material. This relative proportioninpr of the anti-acid and anti-perspirant materials is maintained so that the preparation instantly and completely neutralizes the perspiration on the iingers and will inhibit, to a lesser extent, the formation thereof. The balanced proportions of these ingredients provide a preparation which, when dusted on the lingers, leavesthem only slightly moist and, at Ithe saine time, eiectively neutralizes any perspiration thereon. We have found that in this condition the finger tips are very sensitive and yet not injurious to the materials handled.

Fig. 4 is a fragmentary sectional View of the dispenser shown in Fig. 3.

` 'edients of our preparation are prefloyed in dry powder form and the paraticn itself may be incorporated in a disin such dry powder form or the mixed powd cake. in powder 'l a dispenser such as illustrated in Figs. l and may be utilized. This dispenser' is preferably in the foi-1n of a pad, generally designated Se, which consists of a porous ller material iii which niay be cellu-cotton, crepe paper, or some porous material in the form vof a generous cushion overlaid with a thin layer l5 of absorbent cotton and covered with an appropriate fabric it such as cotton tricot Jersey.

The pad l@ may be fashioned in any desired shape with the fabric coverings Hl stitched together as at i8. The ller material l2 is supplied with a generous amount of the powdered preparation and, when the pad is patted with the fingers, the powdered preparation is applied to the finger tips to neutralize the perspiration and to partially dry the fingers. Pad IQ may be fashioned in various forms depending on the manner and the locus of its use. For instance, the pad be formed as a cuff provided with an elastic which can he worn at the wrists. The pad can also be enclosed within a plastic bag and carried in the purse. IfV desired, the pad may be fashioned as a. roller suitably supported or, as illustrated in Figs. l and 2, the pad may simply be yici-ined as a cushion and provided with a layer "'f of a somewhat adhesive material on one side liu thereof so that it may be adhered to any surface to which it is applied, such as the top of a worlr bench 22.

In Figs. 3 4 there is illustrated a dispenser formed of the preparation ofl this invention as a soli-d cake. When the preparation is fashioned a solid cake, the powdered ingredients are preferably pressed in a mold having a cavity of the desired shape, such as the elongated cake 2d. Cake is preferably formed with a nat bottom face 245 and with a. corrugated top face 2B which tapers downwardly at each end of cake 24. The cake may be housed within a suitable wooden container 35. We have found that the form of cake illustrated in Figs. 3 and 4 provides a very efficient dispenser for the preparation of this in vention. The corrugations insure eiTective contact with the finger tips and, when the nge-rs are rubbed gently thereover, a very thin film of the preparation is applied. The dispenser utiliz ing the solid form of the preparation is also desirable from the standpoint of neatness, since there is no powder nud or residue on the fingers which could transferred to the work pieces being handled. 1t will be appreciated, of course, that the dispenser in solid form may. be fashioned other than as illustrated in Figs. 3 and 4. It may, for example, be formed as a pencil or powder stick, etc. adapted to be carried around in the purse.

- fibrous It will thusbe seen that we have provided a very useful dispenser for applying to the linger tips a preparation which will neutralize the perspiration thereon and inhibit, to a controlled extent, the formation thereof. The dispenser is of special advantage in those industries which require the workers hands to be free of harmful perspiration, and it has been designed to enable its use by the Worker without interrupting his activity and to thereby increase his eiciency.

We claim:

1. A dispenser adapted to dust the fingers with powder when the iingers are rubbed thereover comprising an inner cushion formed oi a porous, material and containing a generous amount of a powder mixture adapted to neutralite perspiration and inhibit the formation thereof, a fabric cover enveloping said cushion, and a layer of absorbent cotton disposed between said cushion and said fabric cover, said layer of absorbent cotton being arranged to absorb said powder from said cushion and said fabric cover being sufficiently porous such that when the lingers are rubbed over said cover the fingers are dusted with the powder contained in said absorbent cotton layer.

2. The dispenser set forth in claim 1 wherein said fabric cover comprises tricot jersey.

3. The dispenser set forth in claim l wherein said powder mixture includes a powder having the property cf neutralizing perspiration, a powder having the property of inhibiting the formation of perspiration, and a powder carrier material for said other powders, said powder having the property of neutralizing perspiration being incorporated in said mixture in an amount far in excess of the amount of said powder having the property of inhibiting the formation of perspiration.
